Build windows, train your brain
A free, cozy stained-glass puzzle game. Carve each board into panes, follow the shapes, and watch the finished window glow into a little mosaic — a grand piano, a fox, a lighthouse at dusk. Three rules, real deduction.
Every pane must be one of the allowed shapes. Touching panes need different colors. Strips keep panes apart, staples hold them together.
More than 2,300 hand-designed mosaic windows to reveal, each with its own palette and mood — dawn, dusk, night. Endless generated puzzles after that. See the windows.
From a two-minute Mini to a properly chewy 8×8 Master. Best times per size, if you like racing yourself.
A properly cozy puzzle: soft colors, rounded type, gentle haptics, and a win animation worth waiting for. No move limits, no penalties — the clock is optional.
